Subject: put_ulong calls in lib_ring_buffer_compat_ioctl() should be compat
X-Git-Tag: v2.1.0~1

put_ulong calls in lib_ring_buffer_compat_ioctl() should be compat

I was noticing the that some of the put_ulong calls in
lib_ring_buffer_compat_ioctl() were not compat_put_ulong.  I can't
imagine this is correct.
